Description
この発明はヒートポンプ装置、特に、電動機を収納した密閉容器を具備する圧縮機を有して冷凍サイクルを実行するヒートポンプ装置に関するものである。 The present invention relates to a heat pump device, and more particularly to a heat pump device that has a compressor including a sealed container containing an electric motor and executes a refrigeration cycle.
従来より、ヒートポンプ装置として、冷媒を圧縮する圧縮機、凝縮器、絞り機構、および蒸発器を順次連結して冷凍サイクルを実行し、凝縮器または蒸発器において冷媒の有する温熱または冷熱を熱媒体に受け渡す(熱移動する)ものがある。
圧縮機は、圧縮機構と該圧縮機構を回転駆動する電動機とを具備し、これらは密閉容器内に収納され、圧縮機構によって圧縮された高圧高温の冷媒は、一旦、密閉容器内に吐出されることから、電動機はかかる高圧高温の冷媒に晒されている。また、圧縮機構の回転を円滑にするため、密閉容器内には機械油(以下「冷凍機油」と称す)が貯められている。Conventionally, as a heat pump device, a compressor, a condenser, a throttle mechanism, and an evaporator that compress refrigerant are sequentially connected to execute a refrigeration cycle, and the heat or cold of the refrigerant in the condenser or evaporator is used as a heat medium. There are things that pass (heat transfer).
The compressor includes a compression mechanism and an electric motor that rotationally drives the compression mechanism, and these are housed in a sealed container, and the high-pressure and high-temperature refrigerant compressed by the compression mechanism is temporarily discharged into the sealed container. For this reason, the electric motor is exposed to the high-pressure and high-temperature refrigerant. Further, in order to facilitate the rotation of the compression mechanism, machine oil (hereinafter referred to as “refrigeration machine oil”) is stored in the sealed container.
電動機は、密閉容器に固定された固定子と、固定子に包囲されて回転する回転子とを具備し、回転子は圧縮機構に接続されている。固定子は筒状であって、外周を形成するバックヨーク部と、バックヨーク部から中心に向かって突出する複数のティース部と、ティース部に絶縁材(インシュレータ)を介して巻き付けられた巻線(電線)と、を具備している。

特許文献1に記載された断熱材であるエステル結合を持たないPPSは、パラジクロルベーンゼンと硫化アルカリを高温高圧下で反応させて得られる[−ph−S−]の繰り返し構造からなる熱可塑性の結晶性エンプラであって、比較的耐熱性に優れ、加水分解の心配がなく、耐熱性が高く、成形性が良く、強度および剛性が高いという特性を有している。しかしながら、溶融成形時において、固化速度が遅いため生産性の悪化を招いたり、バリが出易かったり、微量分解して硫黄ガスを生成することによって金型を腐食させたりするという問題があった。
一方、特許文献2に記載された断熱材であるエステル結合を持つPET、PEN、およびポリブチレンテレフタレータ(PBT)は、加水分解性を有するため、吸水性を有する冷凍機油を使用して、冷媒回路を循環する間に冷媒回路内の水分を吸収する必要があると共に、冷凍機油の吸湿性が高く飽和水分量が大きい場合は加水分解を起こすという問題があった。PPS having no ester bond, which is a heat insulating material described in

Features .
本発明によれば、電動機の絶縁材が、エステル結合を有しモノマー成分として、パラヒドロキシ安息香酸(PHB)を必須成分とし、その他のモノマーとしてベンゼン環を有するものだけをエステル結合で分子の主鎖を構成した全芳香族液晶ポリエステル(LCP)であるため、吸水率が0.01%と極めて低く、油中水分率が1%以下の冷凍機油においては加水分解による絶縁機能の劣化が起り難いから、長期信頼性に優れるヒートポンプ装置を提供することができる。 According to the present invention, the insulating material of the electric motor has an ester bond as a monomer component, parahydroxybenzoic acid (PHB) as an essential component, and only other monomers having a benzene ring as the main component of the molecule.

(絶縁材)
絶縁材7は「LCP」で形成されている。LCPは溶融時に液晶性を示す高分子の総称で、分子構造は複数あり、耐熱性や強度は構成されるモノマーに依存するため一定ではない。
絶縁材7を形成するLCPは、モノマー成分として、パラヒドロキシ安息香酸(PHB)を必須成分とし、以下の添加成分を少なくとも一つ添加した合計で2成分以上のモノマーを共重合(重縮合)して得られる熱可塑性樹脂である。
すなわち、添加成分は以下の5種の少なくとも一成分である。
4、4’−ビフェノール(BP)、
ハイドロキノン(HQ)、
テレフタル酸(TPA)、
イソフタル酸(IPA)、
6−ヒドロキシ−2−ナフトエ酸(BON6)。
例えば、絶縁材7は、PHBとBON6との2成分系である「LCP−A」、または、前記必須成分および前記添加成分の全てを含む6成分系のモノマー(PHB、BP、HQ、TPA、IPA、BON6)を重縮合して得られる「LCP−B」からなる。(Insulating material)
The insulating
The LCP that forms the insulating
That is, the additive component is at least one of the following five types.
4,4′-biphenol (BP),
Hydroquinone (HQ),
Terephthalic acid (TPA),
Isophthalic acid (IPA),
6-hydroxy-2-naphthoic acid (BON6).
For example, the insulating
表1において、LCP−AおよびLCP−Bは、PBT(ポリブチレンテレフタレータ)単体に比べ、吸収率および結晶化潜熱が小さな値になっている。したがって、LCP−AおよびLCP−Bは、耐熱性や抽出性に優れ、成形時の溶融粘度が低く薄肉での流動特性に優れ、溶融状態から固化するまでの熱量移動量が少ないため、固化速度が非常に速く、製造工程においてバリが生成し難いという特性を有している。
また、LCP−AおよびLCP−Bは、示差熱熱量計(DSC)で測定される結晶化潜熱が10J/gであるので、固化速度が速く、製造工程においてバリが出難い。したがって、ハイサイクル成形が可能になり、生産性が良いという特徴を有している。In Table 1, LCP-A and LCP-B have smaller values of absorption rate and latent heat of crystallization than PBT (polybutylene terephthalate) alone. Therefore, LCP-A and LCP-B are excellent in heat resistance and extractability, have low melt viscosity at the time of molding, have excellent flow characteristics in thin wall, and have a small amount of heat transfer from the melted state to solidification. Is very fast, and it is difficult to generate burrs in the manufacturing process.
Moreover, since LCP-A and LCP-B have a latent heat of crystallization of 10 J / g as measured by a differential calorimeter (DSC), the solidification rate is high, and burrs are hardly generated in the production process. Therefore, high cycle molding is possible, and productivity is good.
すなわち、LCPは、エステル結合を有することから、分子構造上は加水分解をするものの、通常の樹脂のようにゴム状に分子が絡まった状態ではなく、剛直な分子が綿密に直線状に配向する液晶性樹脂であることから、吸水率が極めて低い。PBT等のエンジニアプラスチックの吸水率が「0.1%」であるのに対し、LCPの吸水率は「0.01%(23℃、24時間水中浸漬後)」であって、前者よりも一桁以上小さい値になっている。
したがって、絶縁材7を形成するLCPは、耐熱性や抽出性に優れるため、前記何れの冷凍機油および冷媒に対しても安定性が高い。That is, since LCP has an ester bond, it hydrolyzes in terms of molecular structure, but is not in a state where molecules are entangled like rubber like ordinary resins, and rigid molecules are closely aligned in a straight line. Since it is a liquid crystalline resin, the water absorption is extremely low. Engineers such as PBT have a water absorption rate of “0.1%”, whereas LCP has a water absorption rate of “0.01% (after being immersed in water at 23 ° C. for 24 hours)”, which is one more than the former. The value is more than digits.
Therefore, the LCP forming the insulating
図3は、本発明の実施の形態1に係るヒートポンプ装置を説明するものであって、一部(断熱材)の耐加水分解性を示す特性図である。
図3において、縦軸は引張強度保持率(初期の強度に対する試験後の強度の割合)で、横軸は冷凍機油の油中水分率、すなわち、40℃、かつ相対湿度が80%における油中水分(%)である。
冷凍機油を吸湿性の高いエーテル油とし、冷媒をR32冷媒として、両者を入れた容器内に、LCP−A、LCP−B、および比較のためのPBTをそれぞれ、150℃で500時間浸漬したときの引張強度保持率を求めている。FIG. 3 is a characteristic diagram for explaining the heat pump device according to
In FIG. 3, the vertical axis is the tensile strength retention ratio (ratio of strength after the test to the initial strength), and the horizontal axis is the moisture content in the oil of the refrigeration oil, that is, in oil at 40 ° C. and relative humidity of 80% Moisture (%).
When refrigerating machine oil is highly hygroscopic ether oil, refrigerant is R32 refrigerant, and LCP-A, LCP-B, and PBT for comparison are each immersed in a container at 150 ° C. for 500 hours. The tensile strength retention rate is obtained.
このとき、図3から明らかなように、比較材であるPBTは、油中水分率が0.1%であっても、引張強度保持率は60%程度でしかなく、しかも、油中水分率が0.2%になると、引張強度保持率が急激に減少し、油中水分率が0.5%以上では、10%の低い値である。
一方、本発明のLCP−AおよびLCP−Bは、何れも油中水分率が増加するに伴って、引張強度保持率が低下するものの、飽和水分量が2%以下の範囲では、引張強度保持率が70%以上を確保している。
したがって、本発明のLCP−AおよびLCP−Bは、冷凍機油の飽和水分量が2%以下であれば、充分な絶縁機能を保持しており、信頼性の高い電動機6、信頼性の高いヒートポンプ装置100を提供することができる。At this time, as is clear from FIG. 3, the PBT as a comparative material has a tensile strength retention of only about 60% even when the moisture content in oil is 0.1%, and the moisture content in oil. Is 0.2%, the tensile strength retention decreases rapidly, and when the water content in oil is 0.5% or more, it is a low value of 10%.
On the other hand, although both LCP-A and LCP-B of the present invention decrease in tensile strength retention as the moisture content in oil increases, the tensile strength retention is maintained in the range where the saturated moisture content is 2% or less. The rate is over 70%.
Therefore, the LCP-A and LCP-B of the present invention have a sufficient insulation function as long as the saturation moisture content of the refrigerating machine oil is 2% or less, a highly reliable
なお、以上は、2成分系であるLCP−Aと6成分系のLCP−Bとが同様の耐加水分解特性を示していることから、PHBを含む限り、3成分系の全ての組み合わせからなるモノマーや、4成分系ないし5成分系の全ての組み合わせからなるモノマーにおいても、同様の耐加水分解特性が得られている。
なお、LCPは、溶融状態で固体と液体の中間状態を示す樹脂で、いわば棒状の分子がたくさん並んだ状態であり、溶融時そのままに近い状態で固化することが特徴である。すなわち、溶融状態で射出や押出によるせん断力を受けて、さらに分子が綿密に配向することによって、分子間間隙への水分子の侵入、浸透が防止されることが、LPCが加水分解性に優れている理由である。したがって、LCPであるだけで、エステル結合を持つ通常のPETやPBT等の樹脂に対して、加水分解性は断然有利になっている。
また、モノマーの6成分自体も全て芳香環を持った骨格の強い分子で構成された全芳香族系のLCPであるため、さらに加水分解し難いものになっている。In addition, since the two-component system LCP-A and the six-component system LCP-B have similar hydrolysis resistance characteristics, all the combinations of the three-component system are included as long as PHB is included. Similar hydrolysis resistance is obtained for monomers and monomers composed of all combinations of 4-component to 5-component systems.
In addition, LCP is a resin that shows an intermediate state between a solid and a liquid in a molten state, which is a state in which many rod-like molecules are arranged, and is characterized by solidifying in a state close to that at the time of melting. In other words, it is possible to prevent the penetration and penetration of water molecules into the intermolecular gap by receiving the shearing force due to injection or extrusion in the molten state and further precisely aligning the molecules. That is why. Therefore, hydrolyzability is far more advantageous than ordinary PET, PBT, and other resins having an ester bond only with LCP.
In addition, since all six components of the monomer are all aromatic LCPs composed of molecules having a strong skeleton having an aromatic ring, they are more difficult to hydrolyze.
